Queue Scheduling - Planet SGSD-1022 User Manual

4.10.1.4 Queue Scheduling

The Managed Switch uses the Weighted Round Robin (WRR) algorithm to determine the frequency at which it services each
egress queue. The traffic classes are mapped to one of the four egress queues provided for each port. You can assign a
weight to each of these queues (and thereby to the corresponding traffic priorities). This weight sets the frequency at which each
queue will be polled for service, and subsequently affects the response time for software applications assigned a specific priority
value.
Command Usage
WRR controls bandwidth sharing at the egress port by defining scheduling weights for allocated service priorities. When
using WRR, assign a weight of 1-15 to each of the hardware queues.
A queue's weight must be less than or equal to the weight of the next higher priority queue (that is, Q0 Q1 Q2
